What is a VAT Number?

A VAT number is a unique 9-digit code that HM Revenue and Customs (HMRC) sends to businesses. This number is for Value Added Tax (VAT) collection and appeared with a “GB” prefix. For example, GB123456789. However, Brexit (a portmanteau of "British" and "exit”) changed a few things for Northern Ireland businesses. Businesses in Northern Ireland may use “XI” instead of GB when trading with EU partners. For example, XI123456789. Additionally, a VAT number is used on invoices and links the business to its VAT records for tax-related matters.

Why is It Important to Find VAT Number?

Before diving into how to find VAT number, let’s discuss why it is important for businesses to have one. If you are a business based in the UK, you need to verify a VAT registration number to confirm that a business is legitimately VAT-registered. This ensures you are paying or charging the correct VAT and helps you stay compliant with tax regulations set by HM Revenue and Customs (HMRC). It also helps you reclaim VAT on expenses and avoid fraud when dealing with non-compliant businesses. Without a valid VAT number from a supplier, HMRC may reject your claim. And if this happens, you may have to deal with a significant amount of admin to rectify the situation.

How Do You Find Out Your Own VAT Number?

If you are running your own business and wondering how to find VAT number, here is where you can find it:
